3.3 Analysis of Diversity and Richness of
Pollinators Communities
Diversity indices (Species richness, Shannon index) show that the open
trail is comparatively more diverse, followed by the managed habitat
(Table 2). The distribution of the pollinator species was much even in
the open trail followed by Grassland. The species richness and Shannon
Index is significant (t–test, p<0.05) in all of the habitats
types. Similarly, similar evenness is observed in Forest trails and
Grassland.
The highest number of species was found in the open trail (158),
followed by the managed habitat (124), forest trail (103), and grassland
(92). 61 species were common in all of the habitats, while the number of
species exclusively found in one of the habitats was 12 for OT, 6 for
FT, and 3 for MH (Figure 3). While comparing two types of habitats, the
High number of habitats sharing of species was found between Open trail
and Grassland (121) followed by Grassland and Forest trail (97), Managed
habitat and Open Trail (82), and Grassland and Open Trail (68).
